%X <span style=\"font-size:10.0pt;font-family:&quot;\">In this paper, a numerical
wave tank is developed based on High Order Spectral (HOS) method considering
the wave-maker boundary. The 2D irregular wave trains are simulated for a long
time by using this model. The freak wave is observed in the wave train, and its
generation process is analyzed via wavelet analysis. The results show that the
numerical tank can accurately simulate the wave generation and propagation,
even for the freak wave. From the analysis of freak wave generation, it can be
found that, two wave groups with different frequency components superpose together
to form a large wave group. The large wave group modulation generates the freak
wave.</span>
